Tantheem proved a cut above her rivals as she made all the running before storming clear in the Group 3 Prix de Cabourg at Deauville today.
Eight two year olds contested this six furlong race.
At the off Tantheem went into the lead from Blue Tango and Darkanna.
Tantheem continued to lead from Contortioniste and Darkanna next to the rails, while Mister Picnic made ground to the outside.
Tantheem hit the furlong pole under pressure, having drifted across to the rails but from that point onwards careered further and further away.
At the post Tantheem and Mickael Barzalona were roughly four lengths clear of Darkanna and Mister Picnic.
The Freddy Head trained Tantheem, a daughter of Teofilo, had won at Deauville in early July and looks a potentially very smart filly.
